To me it looks shorter. Look at the length of the rear door. And also the c-pillar seems to be thinner.
Anyway, it looks very much like an X5 but the proportions (especially the length of the front door compared to the length of the rear door) are definately different.

so...everyone thinks bmw would put forth the marketing dollars it has already spent to market the x1 (the teaser video released earlier this week) when it actually is marketing the X5 M ? this makes no sense....nor has anyone affirmed a paris unveiling of anything beyond the X1 for BMW
